Battery drain after update 2.44.46 (2025 Q3) on Vertical Watch

jjpaz

@Elipsus I was wearing SV for sleep tracking several weeks ago and battery drain was around 1-2% by night (5-6% daily) so there wasn’t a huge difference. The big difference is if I don’t reset the watch and keeps trying to connect to the BT devices. In that case my daily battery drain was around 17-20% (with same sw version)

@jjpaz I am on Android and I do have battery drain

After unpairing all Bluetooth devices from the watch, including the Suunto app itself (I also forgot the Suunto watch from my iPhone’s Bluetooth list), yesterday at 11:30 a.m. — this morning at 8:00 a.m. I was already down to 17%. So I lost another 10% (a bit more) in 24 hours. There’s clearly another issue that’s not related to Bluetooth.

@fedequei Have you restarted your watch after unpairing all Bluetooth devices? (To make sure there is no more Bluetooth related process still running in background)

fedequei

@sebchastang Yes, I did that at 14:00

Has anyone tried using a different watch face? I’m wondering if certain faces or complications can be causing the drain with newer firmware versions…

Belial

@inkognito yes, I’ve changed the watchface for the least-demanding: only time and date. First, it seemed to help a bit (instead of 10-12%/24h consumption was about 6-8%). Now, after the night with DND-on , watch used 8%
I was considering buying Vertical 2 but, to be honest, something wrong is going on with Suunto’s software development

Has anyone tried standing on one leg screaming this sucks?

I think the sensitivity of the backlight has changed . I believe the watch has somehow become more sensitive in turning the backlight on

Ars Vitae

@thanasis What do you mean exactly? In what sense sensitive?

thanasis

@Ars-Vitae it’s easier to be turned on . I believe (as far as I can tell with one device ) that the backlight is turning on more times that it used to

Yesterday I used my polar h10 chest strap but the h10 was attached to the belt with at just one point, not at to. I do this usually to avoid that the watch and the belt try to connect via Bluetooth to avoid battery drain in my chest strap. But now my watch really often did a “beep” sound without showing something on the watch. After beeing very annoyed I set my watch into flight mode and there was no more beeping. So I think there’s an Bluetooth issue. Now I have disconnected the chest strap and set the watch in flight mode all the time. Will see if this affects battery drain.

@Dimitrios-Kanellopoulos All right, I charged med watch sunday 12.10. 100 % at 19.00. Have 24/7 OHR and had the watch in flight mode all the time. Monday 13.10. 99 % left. That means 1 % battery drain in 16 hours vs. 12 % battery drain a day with blutooth connection on. See my previous post about the behaviour of the HR belt. I think the hotfix has to handle that in order to stopp the battery drain after tha last update.

Belial

@Stefan-Kersting I have something interesting
I’ve tried the same approach with Flight mode - watch is draining as before and syncing (or trying to sync to be more precise) despite flight mode on. I don’t know how this is even possible.

Stefan Kersting

@Belial how is this even possible?

OutdoorMan

@Stefan-Kersting @Belial I think it was discussed somewhere recently, but I cannot find it. But… if you turn off airplane mode via control panel, then all the connections remain on. But if you do it via Settings - Connectivity - Airplane mode, then it turns everything off. I don’t know if it’s a bug or working as designed.

Dimitrios Kanellopoulos

@Belial yes please validate its turned on
